I'm afraid it's impossible. From -ow readme:
"Of course, this breaks the way things are defined, so some applications
might stop working. In particular, expect most commercial databases to
break. Apache and PostgreSQL are known to work, though. :-)"
http://www.openwall.com/linux/README.shtml
But as it was written in days of Linux 2.4.x, the situation could have
changed. A desktop system seems to work.
Thanks,
